Freelancer Overview

My background is in software engineering and full-stack application development with a strong interest in Artificial Intelligence and practical AI implementation. Through freelance development work, I have built and supported software solutions involving API integrations, data processing, automation workflows, and AI-enabled features. This experience has strengthened my attention to detail, analytical thinking, and ability to evaluate outputs for quality, consistency, and usability. While my primary experience is in software development rather than dedicated data labeling roles, I am comfortable working with structured guidelines, reviewing large volumes of information, identifying edge cases, and maintaining high-quality standards. I am particularly interested in AI training, model evaluation, annotation, and helping improve AI system performance through careful analysis and accurate feedback.
